Abstract

The complex [Ru(terpy)(tmen)(OH₂)]²⁺ (terpy = 2,2′:6′2″-terpyridine, tmen = N,N,N′,N′-tetra-methylethylenediamine) and its corresponding oxo complex have been prepared. Their spectral properties and redox properties in aqueous solution were investigated. Evidence for two one-electron redox processes has been obtained for the Ru^IV-Ru^III and Ru^III-Ru^II couples. The reactions of the new ruthenium(IV) oxo species with olefins have been found to proceed with second-order kinetics, rate = k₂[Ru^IV][olefin] where k₂ = (3.3 ± 0.3) × 10^-3 and (2.0 ± 0.2) × 10^-2 dm³ mol^-1 s^-1 at 25°C for norbornene and styrene respectively.
